It may be binding. Have the parties begun to act upon the contract as if it were signed? If so, it would be difficult to deny that a binding agreement was not made. The writing, signed by one party, can be offered as proof of the terms that were orally agreed upon and which are currently in the process of being performed to a material and significant degree. This means that the parties have already made substantial efforts to act as if there was an agreement. It would be more difficult for the party that signed the agreement to prove that it did not intend this writing to be the substance of the agreed upon terms.If a contract is drawn up and one of the parties does not sign it, is it binding?
The parties are generally able to agree to supercede the terms of the prior contract - after all, if they are all the parties to the contract, why should they not be able to have the ability to agree to new terms?Also if at a later date they both agree, verbally, to a different arrangement, does that supercede the first (assuming the first one is binding)?
